Abstract(in English) | The normalized radar cross section (NRCS) of ocean surface in the L- and X-bands is measured from three directions of illumination by an airborne dual-frequency synthetic aperture radar (SAR), and the dependency of the NRCS and the polarization ratio on the relative wind direction is analyzed. In the X-band, the dependencies of the NRCSs in the parallel polarizations show different features each other. The NRCS in the X-band HH polarization has difference between the up- and down-wind conditions, though that in the VV polarization, the NRCSs for the up- and down-wind conditions are almost same. The dependency of the NRCS in the L-band on the wind direction is smaller than that in the X-band. The polarization ratio in the X-band shows the dependency on the wind direction with small difference between the up- and down-wind conditions, though that in the L-band is not apparent. The results suggest the possibility of ocean wind measurement using the polarimetric SAR in the X-band. |
